A short but punchy climb, Bailey Road offers a steady ascent with a few steeper pitches, surrounded by open fields and views of the Coyote Valley. Traffic is usually light, and the pavement is in good condition. It’s not overly long, but just enough to get your heart rate up, perfect for intervals or linking into a longer ride.

The Oak Cove Trail in Calero County Park is a 5.6-mile out-and-back trail open for mountain biking, hiking, and trail running. The trail offers a mix of flat sections and gentle hills, making it accessible for beginners and families. Riders can enjoy scenic views of the reservoir and surrounding landscapes. The trail connects with the Lisa Killough Trail, allowing for extended rides within the park. While the path is mostly flat, there are a few small hills that may require less experienced riders or kids to dismount. The first hill at the beginning (and the last hill on the return) is probably the most challenging.

Los Cerritos Pond is just off the side of the Oak Cove Trail and is a great spot for a pit-stop during your ride. You can get right up next to the banks of the water, or you can hang out under the shade trees closer to the main trail.

True to its name, Los Cerritos ("little hills") Pond is ringed by hills. You'll find a great network of looping walking trails here, and from March through May the wildflowers here are spectacular. Plan to be without shade for long stretches of your run.
